SV-220818r991589: Systems must at least attempt device authentication using certificates. | Microsoft Windows 10 STIG SCAP Benchmark

Assessment Title

Rule Text

Systems must at least attempt device authentication using certificates.

Description

Discussion Text

Using certificates to authenticate devices to the domain provides increased security over passwords. By default systems will attempt to authenticate using certificates and fall back to passwords if the domain controller does not support certificates for devices. This may also be configured to always use certificates for device authentication.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Remediation

This requirement is applicable to domain-joined systems. For standalone or nondomain-joined systems, this is NA.

The default behavior for "Support device authentication using certificate" is "Automatic".

If this needs to be corrected, configure the policy value for Computer Configuration >> Administrative Templates >> System >> Kerberos >> "Support device authentication using certificate" to "Not Configured or "Enabled" with either option selected in "Device authentication behavior using certificate:".
